Bonded Field-Replaceable Rotor Blade Pocket For the CH-54B. Volume 1. Design Study

Abstract

The present CH-54B main rotor blade consists of 28 nonstructural, trailing-edge fairings called pockets. Fourteen of these pockets are different in dimension because of the taper on the blade spar. The adhesive retaining the pockets to the blade is a high-temperature and -pressure system. For these reasons, damaged pockets are repaired at the factory because of high inventory of pockets and sophisticated tooling for the best-curing adhesive would be needed to make a field repair possible. Consequently, under previous contract with the Army (Contract DAAJ02-71-C-0022), the feasibility of developing a pocket and adhesive suitable for field application was investigated. The study resulted in a universal pocket design which could be utilized to replace any pocket on the CH-54B blade and an adhesive system which would cure at room temperature.
